Department of Algebra - Research Seminar

The research group of the Department of Algebra at the Johannes Kepler Universität meets once per week to discuss topics of interest. These include current research, learning topics, and topics of interest to visitors. Guests are always welcome and students are especially encouraged to participate. The meeting also serves as ``Magister- und Dissertantenseminar''. For questions please contact Erhard Aichinger or Günter Pilz.
